  1. aThe significant correlation (t = 0.01); the definition of USECP and LSECP are shown in Table 2; the difference between USECP and LSECP is denoted by SECP_D; SECP_S denotes the sum of USECP and LSECP (SECP_S); Zse_static is skin–electrode static impedance; Φse_static is skin–electrode static phase
